Here is your answer

a)

By Triangle Inequality,

6 + 5 = 11 ( which is greater than the third side >(8) )

5 + 8 = 13. > (6)

8 + 6 =14. > (5)

Hence, the triangle can be formed by the three sides (6,5,8).

b) By Triangle Inequality,

4+4=8 (which is equal to 8 )

Hence, the triangle can't be formed.
